• A. 5 to 10
• B. 25 to 45
• C. 15 to 35
• D. 40 to 60

Answer: (C)

Testicular cancer tends to affect younger men, with most cases diagnosed in the late teens through the 30s. The typical age range is about 15 to 35 years, reflecting the biology of germ cell tumors that arise in the young adult testis. The median age is in the early 30s, and while seminomas often present in the 30s and non-seminomas can appear a bit earlier, the overall distribution centers within the 15–35 window. Ages outside this range are less representative of where most cases occur, since prepubertal ages are very uncommon and incidence in older adults is relatively low compared with this young adult peak. So, the most characteristic age range is 15 to 35.
